RE: IML: 69 Won't pass emmissions

["ernie stepney" <estepney@xxxxxxxxx>]

You didn't mention what kind of carb you're running. The idle test
failure when you leaned it out makes sense as you basically created a
lean misfire. The loaded test however has nothing to do with the idle
screws but with the power circuit. What were your loaded HC and NOx
numbers? If HC was a pass and the NOx was really low you might want to
increase the base timing. If the carb is new I would take it back to the
supplier and have it replaced or at least have the primary cruise
metering circuit fixed. BTW up here in BC we pull the Air Care licenses
of "friendly mechanics".

I did change the oil & filter 2 weeks ago. One thing I'm not sure of is
on 
the new carb, the instructions say to use one vacuum port for timed
advance 
or the other for untimed advance. Since the car has dead when I changed
the 
carb, I couldn't tell for sure which one is correct.
